CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 62/777,081 filed Dec. 8, 2018, which is incorporated by reference herein in its entirety.

FIELD OF THE INVENTION

The present invention relates to building blocks for modular construction. The present invention relates to toy building blocks which are connectable and releaseable.

BACKGROUND OF THE INVENTION Description of the Prior Art

Modular building blocks are used for building mostly static and some dynamic structures for entertainment and educational purposes.

Toy building blocks typically have male and female coupling components. Often, one surface of the block is dedicated to one type of coupling components. Consequently, such blocks are usually connected to one another in a stacking fashion where, a surface, having the female components, frictionally engages with a surface having the male components.

The stacking is usually determined to be in a single direction, and stacking the blocks in orthogonal directions in relation to the determined one is usually not possible.

As a consequence, not all surfaces of the built structures can be evenly patterned with the same structural pattern of coupling components.

Building dynamic structures is usually correlated with the toy building block system's support for relative rotational movement of connected blocks. The types of dynamic structures that can be built are usually very limited.

The universality of a toy building system is usually thought of as a measure of all possible structures that can be built using the system. There are multiple historical patents that attempt to describe a more or less universal toy building block system.

The number of different building block types that are needed in a given system in order to achieve a certain level of universality also differs from system to system. Most of the prior art systems usually have many different block types to achieve some level of universality, which is counter-productive.

The structural integrity of the structures that can be built using some toy building block system, and methods of achieving that structural integrity are also very important aspects of a given toy building block system. These aspects are solved with different levels of success by different inventions.

The object of this invention is toy building blocks which can be stacked in multiple orthogonal directions, which enable even patterning of all surfaces of built structures with the same structural pattern of coupling components, and have above average support for rotation when connected, which can achieve universality of a toy block set with a very small number of block types and have good support for structural integrity of built structures.

Building blocks relevant to this disclosure are discussed in the following U.S. Patents, which are hereby incorporated by reference: U.S. Pat. Nos. 1,216,840; 3,822,499; 6,322,414; 3,005,282; 3,195,266; 5,662,508; 5,061,219; 5,199,919.

SUMMARY OF THE INVENTION

The object of this invention is toy building blocks which can be stacked in multiple orthogonal directions, enabling all surfaces of created structures to be evenly patterned with the same pattern, that have above average support for rotation when connected, can achieve universality of a toy block set with a very small number of block types and have good support for structural integrity of built structures.

To achieve the above mentioned object, the toy blocks of the present invention are elongated cuboid blocks. Each face of an elongated cuboid element of the present invention has at least one coupling component and each elongated face of an elongated cuboid element of the present invention has at least two coupling components. Coupling components on a single face are evenly spaced. The blocks can have only female coupling components or both female and male coupling components. If the block has both female and male coupling components, the female and male coupling components on each elongated face are interleaved so that the neighbouring coupling components on every face of the block of a male coupling component are female coupling components and the neighbouring components of a female coupling component are male coupling components. All the blocks are symmetric with respect to rotation by the right angle with respect to the elongated axis of the block, with possible exception to minor details. All the coupling components on a single elongated face of the block are aligned on the same line.

Having compatible and interleaved coupling components on every face of a block for the mixed block type supports building in multiple orthogonal directions. A single mixed building block type with two coupling components per elongated face is enough to create a universal toy building block set with all the benefits of the above object. The symmetries and arrangement of the coupling components of the blocks also enable even patterning of all surfaces of the built structures with the same structural pattern of coupling components. The elongation of cuboid elements supports building with structural integrity and the creation of dynamic structures can be achieved with rotational symmetry of the female coupling components.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings, wherein like reference numerals represent like parts throughout the various drawing figures, FIG. 1 is a front elevational view of an embodiment of a toy block 100 of length two. The elongated cuboid 100 has four elongated faces. In FIG. 1 only one elongated face is visible, and there is a male coupling component 101 and a female coupling component 102 on that face. Herein we refer to the number of coupling components per elongated face of an embodiment as the length of the block, irrespective of an embodiment's true length in physical space. By way of a non-limiting example, toy building block 100 can have true length of 16 mm, 32 mm, 64 mm The elongated faces of the embodiment 100 have male and female coupling components on them. The male coupling component in the embodiment 100 shown e.g. in FIG. 1 and FIG. 2 is a simple connector peg, and the female coupling component is a simple hole. The cuboid 100 is symmetrical to the rotation by the right angle with respect to the axis of elongation. Therefore, all the elongated faces of the block 100 are identical. FIG. 2 is a perspective view of the embodiment 100 of length two. In FIG. 2, two elongated faces of the block 100 are visible. FIG. 2 also shows one square, nonelongated face of the embodiment 100 which has one male coupling component 101 on it. The opposing square face of the embodiment has a female coupling component on it, which is drawn in dashed line because it is not directly visible. The toy block 100 has in total five male coupling components and five female coupling components.
